Hah, you noticed my post on initial timing.
Thanks for checking it out.
I made it up. Having tuned many combos over the years, I needed to to find shortcuts to speed up the process. Knowing that most iron headed sbms like about 36* of power timing when not octane limited, I still needed to get the T-port sync timing ballparked in a hurry. Having a few distributor timing cams in my kit, it was a simple matter of dropping in the right cam, setting the T-port sync, and fine tuning the rate of advance for the chassis.Over the years, I developed different short-cuts, but this one saved me a lot of fooling around. And when the shop charge is 5 or 6 or 8 times what the poor car-owner makes, time is money, and I'm all about helping the little guys save money. I always had weeks to months of work ahead of me so I was never looking to make big money on individual jobs. That's just stealing IMO.And thieves are destined to destruction.
My turn to be curious, You say you are always looking for sbm stuff. Are you buying and selling, or just looking to gather stuff for the next project?
Oh and what's your definition of "outta hand"; I run 14/34@3400,plus 22ported(another shortcut). My 367 with a 230 cam,likes 48* at 2200 for cruising in overdrive. This is 14 initial, 12 centrifugal at 2200,and 22 in the can. she will accept a lot more at 2200 but that's all I can give her with the current dizzy. She likes over 55* at 2200.The previous cam liked a lot more, with double overdrive and a really lean AFR, returning over 32 mpgUS.
My initial follows the guide perfectly (230 -220)/5 =2 added to 12 = 14*. I tried more but it makes adding centrifugal and ported more difficult, And I lost the bad-boy idle. Smooth idle is not my goal.Stable yes. Rock-solid yes, unflappable yes.Smooth I could care less. If somebody wants smooth, I can install a teener cam.There's your smooth.
I have a dial-back timing gizmo mounted under my dash.I can add or subtract 7 or 8 degrees of timing from the drivers seat. Sometimes when I'm feeling a little pesky, I will crank the idle timing back to 7* at a stoplite. Now the motor is sounding much more potent than it is and I'm intimidating the Mustanger in the next lane. Ima pushing his buttons and I can see he's starting to lose it. When the light turns green he blasts off intending to grind me into powder. Meanwhile, I need a second to put my timing back. And then I take off rather normally. See I pick my spots and I pick my times. I am not like that Mustanger; nobody pushes my buttons.If I am going to risk my ride or my driver's license, or even my life I am gonna do it on my terms.But that DB gizmo sure is fun.......Best tool I ever bought!
